FIG. 2A is a partial schematic top view of a display device according toan embodiment of the disclosure. The structure presented in FIG. 2A maybe one embodiment of the display device 10 of FIG. 1 . In theembodiment, the display device 10 includes a plurality of pixels 100arranged in a matrix, and adjacent pixels 100 in the same columndirection (along the extension direction of a data line 120, that is,the Y direction) may have the same layout design, but the disclosure isnot limited thereto. In the embodiment, among the pixels 100 arranged inmatrix, the adjacent pixels 100 in the same row direction (along theextension direction of a scan line 110, that is, the X direction) mayhave the same layout design, but the disclosure is not limited thereto.Each pixel 100 may be defined by adjacent scan lines 110 and adjacentdata lines 120. In an embodiment, each pixel 100 may be defined by oneside of a data line 120 to the same side of the next data line 120 andone side of a scan line 110 to the same side of the next scan line 110.For example, the pixel 100 can be defined from the left side of the dataline 120 to the left side of the next data line 120, and from the bottomside of the scan line 110 to the bottom side of the next scan line 110,but the disclosure is not limited thereto. FIG. 2B is a partialschematic top view of a display device according to another embodimentof the disclosure. The structure presented in FIG. 2B may be anotherembodiment of the display device 10 of FIG. 1 . In the embodiment, thedisplay device 10 includes a plurality of pixels 100 arranged in amatrix, and layouts of adjacent pixels 100 in the same column direction(along the extension direction of the data line 120, that is, the Ydirection) may be mirrored symmetric, but the disclosure is not limitedthereto. In the embodiment, the adjacent pixels 100 of multiple pixels100 in the same row direction (along the extension direction of the scanline 110, that is, the X direction) have the same layout design, but thedisclosure is not limited thereto. In the embodiment, the scan lines maybe paired. Each pixel 100 may be defined by adjacent pairs of the scanlines 110 and adjacent data lines 120. In the embodiment, each pixel 100may be defined by one side of a data line 120 to the same side of thenext data line 120, and from a midline of the two scan lines 110 in onescan line pair to a half of the distance from the midline of the twoscan lines 110 in said one scan line pair to a midline of the two scanlines 110 in a next scan line pair. For example, the pixel 100 can bedefined by the left side of one data line 120 to the left side of thenext data line 120, and a midline of the two scan lines 110 in one scanline pair to a half of the distance from the midline of the two scanlines 110 in said one scan line pair to a midline of the two scan lines110 in a next scan line pair, but the disclosure is not limited thereto.

Please refer to FIG. 1 , FIG. 2A and FIG. 2B at the same time. In thecross-section and top view of the display device 10, the pixel 100 mayfurther include a display medium (not shown) disposed between thesubstrate 11 and the substrate 13. The scan line 110, the data line 120,switch components 130, pixel electrodes 140, or a common electrode (notshown) may be located between the display medium and one of thesubstrates 11 and 13 to form a driving member and may provide anelectric field to drive the display medium. These pixels 100 can bedisposed above the back light module 12 and allow the light L emitted bythe back light module 12 to pass through to achieve the display effect.

The extension direction of the scan line 110 is different from theextension direction of the data line 120. In one embodiment, theextension direction (X direction) of the scan line 110 and the extensiondirection (Y direction) of the data line 120 may be substantiallyperpendicular, but the disclosure is not limited thereto. The scan line110 and the data line 120 can be disposed in different layers. Accordingto the consideration of the conductivity, the scan line 110 and the dataline 120 are generally made of metal materials, such as aluminum,molybdenum, copper, titanium or similar materials or a combination ofthe foregoing, but the disclosure is not limited thereto. In otherembodiments, other conductive materials such as (but not limited to)alloys or stacked layers with the aforementioned metal materials mayalso be used for forming the scan line 110 and the data line 120.

The pixel electrode 140 is electrically connected to the switchcomponent 130 and provides an electric field to drive the displaymedium. In an embodiment, the pixel electrode 140 and the commonelectrode may be disposed on the substrate 11 and the substrate 13,respectively. In another embodiment, the pixel electrode 140 and thecommon electrode may be disposed on the same substrate, for example, onthe substrate 11, and the pixel electrode 140 may be a film layer underthe common electrode, but the disclosure is not limited thereto.

The display device 10 further includes a light shielding element 200 andan opening 300 defined by the light shielding element 200 in addition tothe pixel 100, and the light shielding element 200 is disposed betweenthe substrate 11 and the substrate 13. In some embodiments, as shown inthe enlarged view of the light shielding element 200, the lightshielding element 200 includes a frame 210 and is disposed on thesubstrate 13 and above the pixel 100, but the disclosure is not limitedthereto. In some embodiments, the light shielding element 200 isdisposed on the substrate 11 and under the pixel 100, but the disclosureis not limited thereto. When a user views an image displayed by thedisplay device 10, the light shielding element 200 may be locatedbetween the pixel 100 and the user. In the embodiment, the lightshielding element 200 may be patterned to define an opening 300, whereinthe opening 300 may be disposed within the range of the pixel electrode140. In this way, the periphery of the pixel electrode 140, the scanline 110, the data line 120, the switching element 130, etc. may besubstantially shielded by the light shielding element 200, and only thearea of the opening 300 allows light to pass through.

The opening 300 defined by the light shielding element 200 determinesthe amount of light L that the display device 10 can pass, that is, thearea of the display aperture. The larger area of the opening 300, thelarger area of the display aperture of the display device 10, but mayalso increase the possibility that areas with poor display effects maybe exposed. The areas with poor display effects may include the areawhere the switch component 130 is located and/or where scan line 110 ordata line 120 is located. For example, when the pixel 100 displays abright state image, the area where the switch component 130 is exposedin the opening 300 may reduce the amount of light L passing through anda dark region may be formed. Therefore, the area where the switchcomponent 130 is located in the pixel 100 may lower the brightness ofthe bright state image, and the pixel 100 may not present a presetbrightness (luminance of bright state), which reduces the display effectof the display device 10, for example, the contrast ratio decreases.Here, the contrast ratio can be understood as the ratio of thebrightness of the bright state image to the brightness of the dark stateimage. When the resolution of the pixel 100 is higher, the size of eachpixel 100 will become smaller, and the proportion of the area with poordisplay effect in the entire pixel 100 will increase accordingly, andthe effect of reducing the display effect will be more obvious. Thelight shielding element 200 may shield the dark region that reduces thedisplay effect, and/or improve the display effect of the display device10, for example, to increase the contrast ratio.

In one embodiment, the light shielding element 200 may cover the scanline 110 and extends toward the pixel electrode 140. At this time, theedge of the opening 300 is separated from the corresponding scan line110 by a distance DA, where the distance DA is, for example, 1micrometer (μm) to 2 micrometer, but the disclosure is not limitedthereto and the distance can be adjusted according to design needs. Inthis way, the light shielding element 200 may cover at least a part ofthe switch component 130, and reduce the dark region where poor displayeffect occurs. Although the design of narrowing the opening 300 mayslightly reduces the area of the display aperture, the dark regionswhere poor display effect occurs may be shielded, which may improve thedisplay effect of the display device 10, such as increasing the contrastratio. In this way, the display device 10 may be applied to ahigh-resolution display, and may increase the contrast ratio and/orimprove the display effect on the premise of slightly reducing thebrightness of the display (luminance of bright state). For example, thedisplay device 10 may have a resolution of more than 1,000 pixels perinch (PPI).

In an embodiment, when the display medium in the display device 10 is aliquid crystal material, a liquid crystal alignment process may beneeded to improve the effect of the liquid crystal material beingdriven. For example, when an alignment directions R and Y direction areintersected at an angle θ in the counterclockwise direction, the liquidcrystal materials is not controlled by the electric field, the liquidcrystal materials will be aligned along the alignment direction R. Whenthe liquid crystal material is controlled by the electric field, theliquid crystal materials will be aligned with the direction of theelectric field. At this time, the polarization state of the light L maybe adjusted when passing through the liquid crystal material, and thenthe adjusted light may pass through a polarizer (not shown) to present arequired brightness. For example, when the light L in a portion of thepixel 100 passes through the liquid crystal material to adjust itspolarization state, if the polarization direction of the adjusted lightis substantially parallel to the absorption axis of the polarizer, thelight L will be mostly absorbed by the polarizer, causing the brightness(luminance of bright state) in the area reduced, so that dark areas ofvisual effect will be presented, such as the dark region BR in FIGS. 2Aand 2B. This is also an area that causes poor display effect. Therefore,the light shielding element 200 may shield the dark region that reducesthe display effect to improve the display effect of the display device10. In an example as shown in FIG. 2A, when the light shielding element200 increases the range of shading, the area ratio of the opening 300relative to the pixel 100 may be within a range of not less than 0.04and not more than 0.06, but the disclosure is not limited thereto. In anexample as shown in FIG. 2B, when the light shielding element 200increases the range of shading, the area ratio of the opening 300relative to the pixel 100 may be within a range of not less than 0.11and not more than 0.19, but the disclosure is not limited thereto.

FIG. 3 is a partial schematic top view of a display device according toan embodiment of the disclosure. The structure presented in FIG. 3 maybe one embodiment of the display device 10 of FIG. 1 . In FIG. 3 , thestructure of the embodiment is substantially the same as FIG. 2B, thedifference lies in the design of the light shielding element 200, so thespecific structure of the display device 10 can refer to the descriptionof the foregoing embodiment, and will not be repeated here. Similar tothe foregoing embodiment, the light shielding element 200 may include aframe 210, and the specific shape and layout of the frame 210 may referto the description of the foregoing embodiment, and will not be repeatedhere.

When the display medium in the display device 10 is a liquid crystalmaterial, as described above, some areas in the pixel 100 will visuallyappear as dark regions, such as the dark region BR in FIG. 2B. The lightshielding element 200 may be designed to shield the area around the darkregion BR. In the embodiment, as shown in a partially enlarged view ofthe light shielding element 200 in FIG. 3 , the light shielding element200 includes the frame 210 and a first protrusion 220. The frame 210 issubstantially arranged along with the contour of the pixel 100, forexample. The frame 210 of the light shielding element 200 may besubstantially a light shielding pattern parallel to the scan line 110and the data line 120, and the first protrusion 220 protrudes from theframe 210 and may be disposed corresponding to the dark region BR. Forexample, the first protrusion 220 may shield at least a portion of thedark region BR, or may completely cover the dark region BR. In addition,the light shielding element 200 may further include a second protrusion230, and the first protrusion 220 and the second protrusion 230 aredisposed at diagonal corners of the frame 210 to shield thecorresponding dark regions BR.

In the embodiment, the first protrusion 220 may have a triangle-likecontour or a quadrilateral-like contour. FIG. 3 illustrates the firstprotrusion 220 with a triangle-like contour as an example, but thedisclosure is not limited thereto. The second protrusion 230 may have atriangle-like contour or a quadrilateral-like contour, and the secondprotrusion 230 may have the same pattern as the first protrusion 220,but the disclosure is not limited thereto. In other embodiments, thecontours of the first protrusion 220 and the second protrusion 230 mayhave different patterns. For example, one of the first protrusion 220and the second protrusion 230 may have a triangle-like contour and theother has a quadrilateral-like contour. In other embodiments, thecontours of the first protrusion 220 and the second protrusion 230 maybe irregular polygons, arcs, or sectors, etc.

The opening 300 defined by the light shielding element 200 is a closedpattern surrounded by a first side S1, a second side S2, a third side S3and a fourth side S4. The first side S1 and the second side S2 are, forexample, defined by the first protrusion 220 and the second protrusion230, respectively, and the third side S3 and the fourth side S4 arearranged parallel to the extending direction (Y direction) of the dataline 120. Here, a distance DB between the opening 300 and thecorresponding scan line 110 may gradually increase from the third sideS3 to the fourth side S4 along the extending direction (X direction) ofthe scan line 110. The opening 300 may be roughly a parallelogrampattern, but the disclosure is not limited thereto. The first side S1and the fourth side S4 of the opening 300 intersect to form a firstacute corner C1. In this way, the first protrusion 220 of the lightshielding element 200 may shield at least a portion of the dark regionBR, or may shield the entire of the dark region BR. In addition, thesecond side S2 and the third side S3 of the opening 300 intersect toform a second acute corner C2. At this time, although the area where thepixel 100 can display is partially shielded by the light shieldingelement 200, the shielded portion is a visually dark region BR or anarea with poor display effect when the back light module (such as theback light module 12 of FIG. 1 ) is turned on, which may increase thecontrast ratio of the display device 10.

If the area of the opening 300 is increased, or if the first protrusion220 is removed, for example, the dark region BR will be exposed in theopening 300, the brightness of the display device 10 when displaying thebright state image will be lower than the expected brightness (luminanceof bright state) and the contrast ratio is reduced. In contrast, whenthe opening 300 has the design as shown in FIG. 3 , the dark region BRmay be shielded by the light shielding element 200 and will not beexposed by the opening 300. The brightness of the bright state imagedisplayed by the display device 10 may be reduced by a smaller extent orleast extent, and the contrast ratio may be improved. Overall, althoughthe design of the opening 300 allows the area where the pixel 100originally allows the penetrating of the light to be partially shieldedby the light shielding element 200 to reduce the overall brightness(luminance of bright state), but the dark region BR may be shielded, andthe contrast ratio of the display device 10 may be improved.

The design of the display device 10 can be applied to high-resolutiondisplay devices or related products. In this type of products, the sizeof the pixel 100 is small and the density of the distribution is high,and the screen door effect generated in the enlarged image is notobvious. In addition, the high-resolution design can achieve a largefield of view (FOV) and present a more stereoscopic and/or realisticvisual effect. And, the display device 10 is suitable for applicationsof virtual reality or augmented reality effects. Due to the small sizeof the pixel 100 and high resolution of the display device 10, thedisconnection lines caused by the unevenness of the display medium, suchas the dark region BR, will have an obvious effect on the contrast ratioof the display device 10. Adjusting the design of the light shieldingelement 200 in the display device 10 to change the size of the opening300 to substantially shield the dark region BR may improve the displayeffect of the display device 10.

FIG. 4 is a partial schematic top view of a display device according toan embodiment of the disclosure. The structure presented in FIG. 4 maybe one embodiment of the display device 10 of FIG. 1 . In FIG. 4 , thestructure of the embodiment is substantially the same as FIG. 2B, thedifference between the two embodiments lies in the design of the lightshielding element 200, so the specific structure of the other componentsand elements in the display device 10 can refer to the description ofthe foregoing embodiment, and will not be repeated here. Similar to theforegoing embodiment, the light shielding element 200 may include aframe 210, and the specific shape and layout of the frame 210 may referto the description of the foregoing embodiment, and will not be repeatedhere.

When the back light module (such as the back light module 12 of FIG. 1 )for the pixel 100 is turned on, some areas will visually appear as darkareas, such as the dark region BR in FIG. 2B, and the light shieldingelement 200 may shield at least a portion of the dark region BR. Inother words, the pattern of the light shielding element 200 can bedesigned to increase the overlapping area of the light shielding element200 and the dark region BR, and the area of the light shielding element200 shields at least a portion of the dark region BR, or the entire ofthe dark region BR.

The dark region BR of the display device 10 roughly locates near thecorner of the pixel electrode 140. In the embodiment, as shown in apartially enlarged view of the light shielding element 200 in FIG. 4 ,the light shielding element 200 includes the frame 210 and a firstprotrusion 240. The frame 210 may be substantially formed by a lightshielding pattern parallel to the scan line 110 and the data line 120,and the first protrusion 240 is protruded from the frame 210. The designof the first protrusion 240 may shield the dark region BR in the displaydevice 10. In addition, the light shielding element 200 may furtherinclude a second protrusion 250, and the first protrusion 240 and thesecond protrusion 250 are disposed at diagonal corners of the frame 210.In the embodiment, the first protrusion 240 has a quadrilateral-likecontour, and the second protrusion 250 may have the same pattern as thefirst protrusion 240, but the disclosure is not limited thereto. Inother embodiments, the contours of the first protrusion 240 and thesecond protrusion 250 may be different. For example, one of the firstprotrusion 240 and the second protrusion 250 may have a triangle-likecontour and the other has a quadrilateral-like contour.

The first protrusion 240 and the second protrusion 250 may respectivelyshield at least a portion of the corresponding dark region BR, or evencompletely shield the dark region BR. In some embodiments, the contoursof the first protrusion 240 and the second protrusion 250 may have apoint-symmetric relationship, but may also be asymmetric with eachother. In another embodiment, the contour and area of the firstprotrusion 240 may be disposed corresponding to the distribution area ofthe dark region BR, and the second protrusion 250 may disposedcorresponding to any one or more of the switch component 130, the scanline 110 and the data line 120.

In the embodiment, the opening 300 defined by the light shieldingelement 200 is, for example, a closed pattern formed by a bended firstside S5, a bended second side S6, a straight third side S7, and astraight fourth side S8. The first side S5 is connected between a bottomend point of the third side S7, and a bottom end point of the fourthside S8. The second side S6 is connected between an upper end point ofthe third side S7, and an upper end point of the fourth side S8. Thedistance DC between the opening 300 and the corresponding scan line 110may be increased from the third side S7 to the fourth side S8 along theextending direction of the scan line 110.

In summary, in the display device of the disclosed embodiment, theopening is defined by the light shielding element, and the patterndesign of the opening corresponds to the dark region of the displaydevice, and the light shielding element may shield at least a portion ofthe dark region, or even all the portion of the dark region. In thisway, the contrast ratio of the display device may be improved, and/orprovide better display quality.
